I've got a question. I know none of you are physicians, and cannot diagnose this over the internet, but I still want to ask.
My left bicep seems to have a decent sized seperation in the muscle, and is visably smaller than my right bicep. The right bicep does not have the seperation to nearly the same degree. I dont feel any WEAKER though... which is the strange part. Is a seperation of the muscle normal?
Are there any dead spaces in the muscle that feel soft, unnatached?
Maybe you just have an odd genetic quirk, if it is just as strong as the other it has adapted to its limitation.
I guess that is all I know without seeing/feeling it.
